Patented Nov. 1, 1932 J OHN'A. H. SIERS, OF JERSEY CITY, NEW JERSEYTERMINAL FASTENING DEVICE Application filed December 10, 1931. SerialNo. 580,010.

This invention relates to fastening devices capable of being applied tothe margins or connecting portions of garments, luggage, etc., andcomprising a series of successive interlocking members adapted to bebrought together or separated by means of a slidable member whichmanipulates the interlocking parts in the required'manner.

The subject-matter of this application is w to provide certainadditional features such that the slidable fastening device describedand claimed in my prior application Serial No. 552,314, filed July 22,1931, may be used in connection with garments, luggage or othercoverings or containers where the edges of the same are to be entirelydisconnected and separated from each other, so as to provide anunobstructed opening.

The object of this invention is, therefore,

2 to provide means whereby the adjacent edges which are connected by theslidable fastening devices described in my prior application may beprovided with a terminal connecting device which, when the slider hasreachedthe end of its travel, will permit detachment and separation ofthe corresponding ends of the slidable fastening device, and also permittheir easy connection when the edges are to be fastened together. Theimprovement will primarily allow the slider to engage the fasteningdevices in the correct way after the ends of the edges of the materialhave been brought together. Thereafter the longitudinal motion of theslider will cause the fastening devices to engage each othersuccessively in the proper manner along the entire edges of thematerial, thereby causing the same to be fastened together.

For a detailed description of one form of my invention which I atpresent deem preferable, reference may be had to the followingspecification and to the accompanying drawing forming a part thereof, inwhich Fig. l is a plan view, partly in section, showing my improvedterminal fastening device in position, one-half only of the slider beingshown.

Fig. 2 is a plan view of the lower end thereof, as shown in Fi 1, butshowing the end to of the complete sli er.

Fig. 3 is a perspective view of one member of the terminal fasteningdevice.

Fig. 4 is a perspective view of the opposite member of the terminalfastening device.

Fig. 5 is a plan view of the slider, and

Fig. 6 is an end view of the same.

Referring to the drawing, it will be seen that the numeral 1 indicates asuitable strip of fabric or other material, preferably in the form of atape, on which the interlocking elements 2 and 3 are mounted orfastened. The general shape and action of these fastening devices arepreferably substantially in accordance with the detailed descriptionthereof set forth in my prior application, above mentioned.

In Fig. 1, two pairs of such interlocking elements are shown as beingcarried by the fabric. Below said pairs, the successive memhere aresimilar to the interlocking members, but are not provided withprojections or slots, as they are more in the nature of spacing elements4:, which serve to determine the position of the lower terminalfastening member 5 and its complementary fastening member 6. The spacingelements 4 are shown to be without interlocking parts, in order that theedges of the material to which the fasteners are attached may be movedrelative to each other and separated, as will be hereinafter described.

One portion, or the hooking member 5, of the terminal fastening device,is illustrated in Fig. 3. This comprises a portion adapted to beconnected with the fabric, as are the other members of the fasteningdevice, that is, through the use of tapering or projecting prongs 7. Theopposite side of said terminal fastening member is provided with twohooks, having reversely bent outer portions as indicated at 8, in Fig.3.

The opposite member 6, .of the terminal fastening device, is similar tothat just described, except that it is provided with no hooks. It ismade slightly longer than the spacing elements 4, and is provided withtwo sets of prongs 9. Both of these members are provided with groovessimilar to those of the interlocking members 2 and 3, as indicated inthe drawing. The slidable device which causes the members to interlockand is usually termed the slider is illustrated in Fig. 5, and consistsof two similar or correspondingly shaped parts 10 and 11, which are heldtogether by suitable pins, as indicated at 12, which pins pass throughslightly raised bosses 13 that serve to separate the flanged parts ofthe slider the required distance. As described in my prior application,this slider includes a grooved portion, the upper end of which branchesinto separate grooves which are formed by the centrally raisedtriangular projection and by the flanged margins on the opposite sides10 and 11; One portion of this member is also provided with acylindrical part 14, through which a bar 15 of the handle 16 may bepassed.

Referring now to Fig. 1, it will be seen that when the member 5 carryingthe books 8 is attached to the fabric 1, the upwardly projecting part ofthe hooks will be adapted to engage the grooves of the complementaryterminal fastening member 6. \Vhen the slider is pushed downward todisengage the interlocking elements of the fastener, the flanges on itslower end will contact with the ends of the hooks 8, which will stop itsdownward motion as indicated in Fig. 1. The interlocking members havingbeen separated by the terminal portions and spacing elements, theleft-hand strip of fabric 1 with the various members carried thereon maythen be slid upward so that the hooks 8 are disengaged from the slots inthe terminal fastening member 6. Thereafter the edges of the garment orcontainer on which the fastening members are mounted may be entirelyseparated, and the edges of the coat, garment, or container thrown openany dis tance. In closing the opening between the edges of the garment,or container, the lower terminal member 6 is first placed over the hooks8 and then the slider is moved upward in the usual manner, to cause theinterlockprior application.

Having thus described this form of my invention, I do not wish to beunderstood as being limited to the details of form or specificarrangements of parts herein set forth, for various changes may be madein the design of the terminal fastener without departing from the spiritand scope of my invention, as set forth in the appended claims.

What I claim and desire toprotect by Letters Patent, is

1. Terminal fastening means for uniting the ends of series ofcomplementary interlocking fasteners, comprising, a terminal member forone of said series, provided with hook portions having ends extendingsubstantially parallel with the direction of the successive fasteners ofsaid series and with transverse grooves, and a complementary terminalelement having transverse grooves that are used to receive said hookingportions, whereby said terminal members may be hooked together andunhooked when said series of fasteners are disengaged.

2. Terminal fastening means for the ends of series of groovedinterlocking fasteners having laterally extending bases, which comprisesa male member having two hooks thereon comprising reversely bentportions extending parallel with the base thereof and a complementaryfemale member having two transverse grooves above the base thereof andadapted to receive said hooks on the firstmentioned member, whereby saidmembers may be unhooked after said interlocking fasteners have beendisengaged.

3. Separable fastening means comprising two series of interlockinggrooved elements having laterally extending bases, one series beingprovided with enlarged heads and having a terminal element carryinghooks comprising reversely bent portions extending parallel with thebase thereof, and the other series being provided with a slot in eachele- ,ment through which the heads of the 0pposite series may pass andwithin which they are retained, the terminal element of said secondseries having transverse recesses extending parallel with the basethereof adapted to receive the hooks of the opposite terminal element,and a flanged slider whose flanges are adapted to enter the grooves inthe elements of both series, the ends, of said bent portions on saidhook element forming stops for said slider, and whereby said terminalelements may be unhooked after said interlocking elements have beendisengaged.
